对象数组

.代码如下：

package Day05; public class TestCircle1 {

public static void main(String[] args) {

// Circle c1 = new Circle(1.0);

// Circle c2 = new Circle(2.0);

//

// c1.setRadius(10.0);

// System.out.println(c1.getRadius());

// System.out.println(Circle.getName()); // Circle c3 = new Circle(1.0);

// printAreas(c3, 5); Circle[] cArray1 = createCircleArray();

printCircleArray(cArray1);

} private static void printCircleArray(Circle[] cArray) {

for (int i = 0; i < cArray.length; i++) {

System.out.println(cArray[i].getRadius() + "\t" + cArray[i].getArea());

}

double sum = 0.0;

for (int i = 0; i < cArray.length; i++) {

sum += cArray[i].getArea();

}

System.out.println(sum); } private static Circle[] createCircleArray() {

Circle[] cArrayReturn = new Circle[5];

for (int i = 0; i < cArrayReturn.length; i++) {

cArrayReturn[i] = new Circle(Math.random() * 100);

}

return cArrayReturn;

} private static void printAreas(Circle circle, int times) {

for (int i = 0; i < times; i++) {

System.out.println("The circle's area is: " + circle.getArea());

circle.setRadius(circle.getRadius() + 1);

} }

}

希望有帮助，我也是为了复习
